{In this mountain} (en t(9369) orei tout(9369)). Jacob's Well is
at the foot of Mount Gerizim toward which she pointed. Sanballat
erected a temple on this mountain which was destroyed by John
Hyrcanus B.C. 129. Abraham ( Ge 12:7 ) and Jacob ( Ge 33:20 ) set
up altars at Shechem. On Gerizim were proclaimed the blessings
recorded in  De 28 . The Samaritan Pentateuch records an altar
set up on Gerizim that is on Ebal (over 200 feet higher than
Gerizim) in the Hebrew ( De 27:4 ). The Samaritans held that
Abraham offered up Isaac on Gerizim. The Samaritans kept up this
worship on this mountain and a handful do it still. {And ye say}
(kai humeis legete). Emphasis on humeis (ye). Ye Jews. {Ought
to worship} (proskunein dei). "Must worship," as of necessity
(dei). The woman felt that by raising this theological wrangle
she would turn the attention of Jesus away from herself and
perhaps get some light on the famous controversy. Proskune(935c) in
John is always worship, not just respect.
